ASTM A572 Steel, grade 60 Product Information -:- For detailed product information, please contact sales. -: ## **Product Datasheet: ASTM A572 / A572M Grade 60 Steel** **Product Overview** ASTM A572 Grade 60 is a **high-strength low-alloy (HSLA) structural steel** offering a significant increase in strength over standard construction grades, with a guaranteed **minimum yield strength of 60 ksi (415 MPa)**. This grade represents the high-strength tier of the widely used A572 series, providing approximately 20% greater yield strength than Grade 50. Through precise **columbium (niobium) or vanadium microalloying**, it achieves enhanced mechanical properties while maintaining good weldability and toughness. Grade 60 is engineered for applications where maximizing structural efficiency, reducing member size, or handling higher design loads is critical. It is available in plates, structural shapes, and bars. **Key International Standards** * **Primary Standard:** **ASTM A572 / A572M** - Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel. * **Governing Specification:** This product conforms to all requirements for **Grade 60**. * **Microalloying System:** Strength is achieved via grain refinement and precipitation strengthening from controlled additions of **Columbium (Cb/Nb)**, **Vanadium (V)**, or a combination. * **Heat Treatment:** Typically supplied in the **as-rolled** condition. For plates, especially in thicker sections, **normalizing** is often specified to ensure uniform through-thickness properties and optimal toughness. * **Related Standards:** Comparable to international grades such as **JIS G3106 SM570** and **EN 10025-2 S460NL** (for normalized material). It is a common bridge material between standard structural steels and quenched & tempered plates. **Chemical Composition (Weight % - ASTM A572 Grade 60 Requirements)** Chemistry is balanced to deliver higher strength while maintaining fabricability, with controlled carbon and manganese levels. | Element | Requirement (Max, unless noted) | Purpose & Note | | :--- | :--- | :--- | | **Carbon (C)** | 0.26% | Controlled for strength and weldability balance. | | **Manganese (Mn)** | 1.35% | Solid solution strengthening. | | **Phosphorus (P)** | 0.04% | Impurity control. | | **Sulfur (S)** | 0.05% | Impurity control. | | **Silicon (Si)** | 0.40% | Deoxidizer. | | **Columbium (Cb/Nb)** | 0.05% Max (if added) | Primary grain refiner. | | **Vanadium (V)** | 0.15% Max (if added) | Precipitation strengthener. | | **Carbon Equivalent (C.E. IIW)** | -- | Typically 0.42 - 0.50, indicating weldability that requires **controlled procedures**. | **Physical & Mechanical Properties** | Property | Requirement (ASTM A572 Grade 60) | Typical Performance & Significance | | :--- | :--- | :--- | | **Yield Strength (Min)** | 60 ksi (415 MPa) | Typically 63 - 73 ksi (435 - 503 MPa) | | **Tensile Strength** | 75 ksi (515 MPa) min | Typically 80 - 90 ksi (552 - 621 MPa) | | **Elongation in 2" (Min)** | 17% | Maintains adequate ductility for structural performance. | | **Yield-to-Tensile Ratio** | Not specified in A572. | Typically 0.78 - 0.85. | | **Modulus of Elasticity** | ~29,000 ksi (200 GPa) | Standard for steel. | | **Atmospheric Corrosion Resistance** | ~2x carbon steel (if Cu ≥ 0.20% specified). | Optional feature. | | **Key Feature** | **High-Strength Microalloyed Workhorse:** Delivers 60 ksi yield strength through cost-effective microalloying, offering a viable alternative to more expensive quenched & tempered steels for many applications where extreme toughness is not the primary driver. | **Product Applications** ASTM A572 Grade 60 is specified for demanding structural applications where strength and weight efficiency are paramount. * **Bridge Construction:** Primary girders (especially welded plate girders), truss members, and splice plates in medium to long-span bridges. * **Heavy Industrial Structures:** Columns, transfer girders, and crane runway beams in mills, power plants, and processing facilities. * **Mobile Crane & Heavy Equipment:** Boom sections, outrigger pads, and main frames where high strength-to-weight ratio is critical for performance. * **Material Handling:** Structural components for high-capacity stacking cranes, shipyard gantries, and large conveyors. * **Building Construction:** Heavily loaded columns in high-rise buildings, long-span trusses, and moment-resisting frames in seismic zones (when toughness is verified). * **Transportation:** Chassis components for specialized heavy-haul trucks and trailers. **Advantages & Fabrication Notes** * **Controlled Weldability:** Welding requires established procedures due to the higher strength and carbon equivalent. * **Preheat:** **Generally required.** AWS D1.1 recommends preheat for Grade 60 material. Typical range is **200-350°F (93-177°C)**, depending on thickness and restraint. * **Low-Hydrogen Practice:** Mandatory. Use of matching strength, low-hydrogen electrodes (e.g., E80XX, E90XX series). * **Procedure Qualification:** Welding Procedure Specifications (WPS) should be qualified per applicable codes (AWS D1.1, D1.5). * **Good Formability with Consideration:** Can be cold formed, but requires larger bend radii and more force than lower-strength grades. Hot forming is commonly used for complex shapes. * **Strength Efficiency:** Enables significant reductions in member size and weight compared to Grade 50, offering potential savings in material, fabrication, and transportation. * **Toughness & Supplementary Requirements:** For critical applications (fracture-critical members, dynamic loading, low-temperature service), it is **essential to specify supplementary impact testing (ASTM A6 S1)** to guarantee adequate Charpy V-Notch toughness. **Disclaimer:** This datasheet describes **ASTM A572 Grade 60**. For procurement, clearly specify the **standard (A572), grade (60), product form, and condition** (e.g., normalized for plates over 1.5"). **Critical Considerations:** 1. **Not an A992 Equivalent:** For wide-flange shapes, A992 is typically specified for 50 ksi yield. Grade 60 shapes are a separate product with higher strength. 2. **Welding is Specialized:** Fabricators must have experience with high-strength steels. Improper welding can lead to hydrogen cracking or inadequate joint strength. 3. **Connection Design:** Bolted and welded connection designs must account for the higher strength. Oversizing bolts or using undersized welds relative to the base metal strength can lead to connection failures. 4. **Toughness is Not Automatic:** The base A572 specification does not require impact testing. **For any load-carrying application, impact testing should be specified** to define minimum toughness at the project's service temperature. 5. **Availability:** Confirm availability with suppliers, as production runs for Grade 60 may be less frequent than for Grade 50. This grade is a powerful tool for structural optimization but demands respect for its fabrication requirements and the need for explicit toughness certification in most structural applications. -:- For detailed product information, please contact sales. -: ASTM A572 Steel, grade 60 Specification Dimensions Size： Diameter 20-1000 mm Length <4719 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: ASTM A572 Steel, grade 60 Properties -:- For detailed product information, please contact sales. -:
